Det. Don Lupi released a statement Wednesday announcing that the department has contacted Crime Stoppers to help solve the case. The investigation began on Jan. 5 after four downtown businesses realized they were victims of break-ins, with one reporting that cash had been stolen between closing on Jan. 4 and opening the next morning.

“In this new age of technology, it’s important we give the public different means of contact,” Lupi said in a statement. “Some people feel comfortable sending an email or Facebook message while others might feel more comfortable giving an anonymous tip. We are encouraging the public to work with us in any way that they feel comfortable.”

The areas of each business where cash was stored were ransacked, but nothing was reported stolen from the Spotted Dog Wintery, The Cobblestone Rose Gift Shop and Maureen’s Designs. Cash was stolen from Mac’s, according to police.

All of the businesses showed signs of forced entry, usually through doors that were kicked in, according to police.

Anyone with information on these crimes is encouraged to contact Crime Stoppers at 1-800-SPEAK UP (1-800-773-2587), or online at www.1800speakup.org. Tips also can be texted to CRIMES (274637).
